SELECTIVE LUBRI CANT DISTRIBUTOR Filed March 50, 1929 2 Sheets-Sheet 2SNVENTOR 13a ciza dfl Wear/2e ATTORNEY Patented July 12, 1932 Parentorriee RICHARD D. WEAR'NE, OF GARY, INDIANA SELECTIVE LUBRICANTDISTRIBUTOR Application filed March 30, 1929. Serial No. 351,442.

This invention relates to improvements in selective lubricantdistributors. One important object of the invention is to provide adevice having a multi-port control whereby the device can be adjusted ormanipulated to distribute predetermined amounts of lubricant underpressure to different machines consecutively or to a selected machineonly.

A further object of the invention is to provide a novel and simpleconstruction of distributor which is. capable of ready installation andwhich is thoroughly eificient and practical in use.

With the foregoing and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangements of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 is a longitudinal sectional viewtaken through the distributor, the body of the same being foreshortened.

Figure 2 is a top plan view of the main casin of the distributor withthe operating handles removed.

Figure 3 is an elevation of the handle-carrying end of the distributor,portions of the. operating handles being shown as broken off.

Figure 4 is a diagrammatic sectional view 1 taken through one of thedistributing tubular members showing the relative position of the portstherein for controlling distribution.

Figure 5 is a section on line 5-5 of Figure 2 with the distributingports disaligned.

Figure 6 is a view similar to Figure 5 show-' ing two of thedistributing ports alined with one of the outlet ports of the maincasing,

the view being taken on line 5-5 of Figure'2. Referring to the drawings,the numerals 7 designate supports for a main casing 8 of the presentdistributor which, as illustrated, is

provided with a longitudinal cylindrical bore 8 and with a plurality ofdiametrically disposed outlet ports 9 communicating with thelongitudinal bore 8, each of the ports being provided with pipeconnecting threads 10 adj acent the upper face of the main casing. V

, A removable plug or cap 12 is fitted in one end of the main casing,while at the opposite end is a fixed dial 13 having a rim 14 provided 5with a plurality of recesses 15 adjacent each dial number. v

A tubular member 16 is mounted-within the bore of the main casing andterminates shortrof the cap 12 to provide an inlet chamber 17 whichcommunicates with an inlet connection 18 of the main casing so thatlubricant under pressure may be supplied to said cham-. ber 17. Areduced end 19 of the tubular member 16 projects exteriorly ofthe maincasing 5 and is packed, as at 20, so that a retaining ring 11 whichthreadedly engages the main casing and holds the parts in position, willalso prevent longitudinal movement of the tubular member.

. Fitted upon the outer extremity of the reduced end.19 is a disk 21having alug 21 which functions as a key for coupling the same with thetubular member 16 for unitary rotation. Said disk has formed integral 5therewith an indicating member or pointer 22 and an operating handle 22,the latter beingconstructed in two sections connected by a hinge 25 sothat the outer section 24: may yield but be held in normally alinedposition so by means of a spring 23. The outer section is provided witha locking recess 27, the purpose-of which will presently appear, andwith a lug 26 which latter normally engages one of the recesses 15 tolock the handle 22 against rotation and at the selected point upon thedial 13.

An inner sleeve or tubular member 28 fits telescopically the tubularmember 16 and a sealing member 29 threadedly engages the in- 0 ner openend of the sleeve 28 and has a tubular projection 30 disposed in thechamber C of the member 28. Ports 31 are formed in the member 29 andcommunicate with the chamber 17 so that the lubricant is directedtherethrough into the hollow portion 32 of the sealing member 29 and, aswill later appear, into the chamber C. Mounted within the cap 12 andlocated within the hollow pormo tion 32 of the member 29, is acylindrical plunger 33 equipped with a gasket 34. This plunger isthreaded, as at 36, to internal threads 37 of the cap 12 so that uponmanipulation of a hand-wheel 38 on the plunger the pressure upon theplunger regulated accordingl A port 39 is provided within the chamber 32and is controlled by ball valve 40, engaged by a spring 41 exerting apressure upon said ball to hold it upon its seat. Said spring 41 isretained in place by means of a pin 42. A port 43 is provided throughthe wall of projection 30 beyond the port 39 so that the lubricant issupplied into the chamber C.

Attached to the manipulating end 44 of the inner tube 28 by means of ascrew 46 is a handle 47' which is provided with a locking pin 48 toengage the opening 27 of the section 24 of the handle 22, the purpose ofwhich will presently appear. Also carried by the handle at the oppositeside thereof is a pointer 49 for cooperating with the Zero indication ofthe dial 21.

The tubular member 28 is provided with a plurality of spirally arrangedports 50, as illustrated diagrammatically in Figure 2, and uponsubstantially the upper 180 or half of the circumference of said member,while formed in the outer sleeve or tubular member 16 is a similarnumber of ports 51, said ports 50 and 51, when alined, as illustrated inFigure 6, communicating with their respective outlet ports 9 so thatlubricant from the chamber C will be distributed to such selected outletport.

The ports 51 in the sleeve 16 are also an ranged spirally, and willassume the various numbered positions illustrated so as to correspondwith the dial numbers upon the dial 13, indicating at a glance by theposition of the pointer 22 the positions of the respective ports 51 withrelation to the outlet ports. 9.

In the present construction, when the levers or handles 22 and 47 areinterlocked or connected at openings 27 and pin 48, the ports 50 and 51of the respective sleeves are inv registry. In this condition, startingat zero and turning the said handlesunitarily in a clockwise direction,will effect the discharge of lubricant therethrough. and through theoutlet ports 10 consecutively.

Should discharge of lubricant through any individual port 10 to theexclusion of the other ports 10 bedesired, the handles or levers arefirst moved to neutral positions as indicated by their pointers. Thenwith such levers disengaged at 2748, lever 22 is turned to the desiredport as indicated by pointer 22 on the dial 14 and lever 47 is turn-eduntil pointer 49 coincides with zeromark 45 which will align the desiredports.

It is also apparent from the arrangement and construction of the pumpplunger that the pressure may be increased and thus assist in forcingthe same into the chamber C after having been admitted into the hollowportion 32.
